Raspberry Pi, This tutorial is about the Voice Recording and Test to speech Using Raspberry Pi. But First, let's have a small introduction about Raspberry Pi. Introduction Raspberry Pi 3 Model B System on Chip(SoC) What is System on Chip?                 - A complex IC that integrates the major functional elements into a single chip or chipset. Programmable processors On-chip memory Accelerating function hardware (e.g. GPU) Both hardware and Software Analog components Benefits of SoC                   - Reduce overall system cost                   - Increase performance                   - Lower power consumption                   - Reduce size Soc in Raspberry Pi: Broadcom BCCM2835 SoC Multimedia Processor CPU             - ARM 1176JZF-S (armv6k) 700MHz             - RISC Architecture and low power draw             - Not compatible with traditional PC software GPU             - Broadcom Video IV             -

Hey Folks, In this tutorial, we will learn how to interface a Seven Segment Display with ARM(FRDM-KL25Z). Components Required FRDM-KL25Z board Seven Segment Display (Common Cathode) Breadboard Mini Jumper Wires (As Required) FRDM-KL25Z         2. Seven Segment Display        3. Breadboard Mini         4. Jumper Wires (Male to Male)   Follow the Image below for circuit connection reference:-  (Interfacing all components) After making the circuit dump the code given below:- #include "mbed.h" BusOut display(PTA1,PTA2,PTD4,PTA12,PTA4,PTA5,PTC8,PTC9); int main() {          while (1) {                 display= 0xBF ;         wait( 1 );         display= 0x86 ;         wait( 1 );         display= 0xDB ;         wait( 1 );         display= 0xCF ;         wait( 1 );         display= 0xE6 ;         wait( 1 );         display= 0xED ;         wait( 1 );         display= 0xFD ;
